Load Image dalam JInternalFrame

arumsha ♦ April 23, 2012 ♦ Leave a Comment

Post ini dibuat dengan salah satu alasan yaitu mengurangi penasaran saya terhadap pertanyaan teman. Pertanyaannya adalah bagaimana load image di internal frame sehingga pada nantinya framenya bisa diminimize/maximize. Oh ya hampir lupa, kita disini belajar mengenai Java, jadi program yang akan kita pakai juga java. Saya menggunakan Netbeans 7.0, dimana untuk look and feel user interfacenya, saya masih import manual. Kurang lebih output programnya seperti ini.

Program dijalankan kemudian klik tombol browse, yang artinya memilih file gambar yang akan diinginkan, disini saya tidak menggunakan file filter untuk menyaring mana aja file yang akan diambil sebagai gambar. Setelah gambar dipilih dan klik tombol Open maka akan keluar tampilan seperti dibawah :

kGambar akan otomatis muncul dalam internalframe, dan selanjutnya bisa di minimize dan di maximize.

Baiklah kita langsung buka saja netbeansnya, silakan buat project baru, dan buat JFrame baru, silakan design sesuka hati. Tinggal drag and drop, untuk aturan mainnya sebelum memasukkan jinternalframe, drag dulu JDekstopPane nya. Setting di properties dengan klik kanan pada komponen JInternalFrame nya, aktifkan icon minimize dan iconifiable. Kurang lebih inspector dan design nya seperti gambar berikut :

Setelah membuat tampilan alias design, perhatikan dalam internalframe ada layout yang harus disetting yaitu BorderLayout, tinggal klik kanan pada komponen JInternalFrame, pilih SetLayout>>>BorderLayout. Kurang lebih code nya simpel begini :

Matrix : Random Binary ~ Java

arumsha ♦ April 15, 2012 ♦ Leave a Comment

This is an example of matrix two dimension which is contain binary random. We can use class Random in Java

public class RandomBinarySet {
    public static void main(String[] args) {
        Random random = new Random();
        int[][] inputArray = new int[5][5];
        for (int i = 0; i < inputArray.length; i++) {
            for (int j = 0; j < inputArray[i].length; j++) {
                int result = random.nextInt(2);
                System.out.print(result+"\t");
            }
            System.out.println();
        }
    }
}

“int result = random.nextInt(2);” means that the value limited to binary ( is not more than 2). And below the output :
